.
<pre>

Write an equation as you read the problem

    P + B = 470000,


and then

    x + (x-90000) = 470000


(x stands for P = Pierre).


Continue

    2x = 470,000 + 90,000 = 560,000

     x                    = 560000/2 = 280000.


<U>ANSWER</U>.  $280,000 for P  and  $280,000 - $90,000 = $190,000 for B.
